The mud flaps are good but I did not use the self taping screws. The self taping screws strip to easily
reccomend stainless sheet metal screws and drill a small hole

Seem to be good quality but not the easiest to install. No premarked or drilled holes. Vague instructions.  Plan on a longer install time than you would expect.

The guys who put my bracket and High Country Mud Flaps on said it was the best and easiest set up they have ever seen.
The installation was fast and easy but sturdy with the heavy duty mats.
I would recommend them to anyone and everyone if they are looking for mud flaps

This High Country logo Gatorback Dually Mud Flap set is designed for a perfect fit. The rear flaps offer 21" of heavy duty rubber and weigh in at 10 lbs each. This weight will ensure that they do not sail when you are driving and they do their job. The rear pair come with the custom fit brackets and the holes that line up to the factory fasteners already routered into the flaps along with all of the hardware and brackets needed for installation. The heavy duty rubber ensures that there will not be any debris that gets passed these flaps. The front flaps install inside the wheel well overtop of the existing factory mud flaps for extended protection.

The High Country logo is officially licensed ensuring it looks perfect and is die stamped into the stainless steel plate with a hand applied vinyl overlay. The stainless plate measures 10 1/4" x 5" on the front and the rear plate measures 17 1/4" x 5". You will appreciate the attention to detail in these flaps.

Installation is made straight forward with the included self tapping screws and custom rear bracket. The front flaps will fasten directly to the lip of the wheel well with the self tappering screws. You can use factory existing fasteners if your wheel well has those available. There needs to be at least 1/2" of clearance in the front between the tires and wheel well to accomidate the thickness of the flap. The rear flaps will be fastened to the rear bracket and one or two self tapping screws to hold it tight against the wheel well. This will prevent the flaps from flapping into the tires and getting tore off. The Gatorbacks install flush to the inside of the wheel well so they work with step bars, power boards or side steps. The mudflaps also feature a lifetime warranty on the rubber portion of the flap. If the flap comes off the truck or is damaged to due to normal wear and tear, let us know and we will send you a replacement piece of rubber at no charge.
